About Hackers

In the Computer security context, a hacker is someone who seeks and exploits weaknesses in a computer system or computer network. Hackers may be motivated by a multitude of reasons, such as profit, protest, challenge, enjoyment,^[1] or to evaluate those weaknesses to assist in removing them. The subculture that has evolved around hackers is often referred to as the computer underground.^[2]
There is a longstanding controversy about the term's true meaning. In this controversy, the term hacker is reclaimed by computer programmers who argue that it refers simply to someone with an advanced understanding of computers and computer networks,^[3] and that cracker is the more appropriate term for those who break into computers, whether computer criminal (black hats) or computer security expert (white hats)^[4][5] - but a recent article concluded that: "...the black-hat meaning still prevails among the general public"

hackers are 3 types

white hat 

black hat

grey hat :-

A grey hat hacker lies between a black hat and a white hat hacker. A grey hat hacker may surf the Internet and hack into a computer system for the sole purpose of notifying the administrator that their system has a security defect, for example. They may then offer to correct the defect for a fee.^[20] Grey hat hackers sometimes find the defect of a system and publish the facts to the world instead of a group of people. Even though grey hat hackers may not necessarily perform hacking for their personal gain, unauthorized access to a system can be considered illegal and unethical.
